to a Map via decoration.
|
AbstractOrderedMapDecorator |
Provides a base decorator that enables additional functionality to be added
to an OrderedMap via decoration.

be removed by the garbage collector.
|
AbstractReferenceMap.ReferenceEntry |
A MapEntry implementation for the map.
|
AbstractReferenceMap.ReferenceStrength |

|
CaseInsensitiveMap |
A case-insensitive
Map . |
CompositeMap |
Decorates a map of other maps to provide a single unified view.
|
CompositeMap.MapMutator |
This interface allows definition for all of the indeterminate
mutators in a CompositeMap, as well as providing a hook for
callbacks on key collisions.
|
DefaultedMap |
Decorates another
Map returning a default value if the map
does not contain the requested key. |
EntrySetToMapIteratorAdapter |
Adapts a Map entrySet to the MapIterator interface.
|
FixedSizeMap |
Decorates another
Map to fix the size, preventing add/remove. |
FixedSizeSortedMap |
Decorates another
SortedMap to fix the size blocking add/remove. |
Flat3Map |
A
Map implementation that stores data in simple fields until
the size is greater than 3. |
HashedMap |
A
Map implementation that is a general purpose alternative
to HashMap . |
LazyMap |
Decorates another
Map to create objects in the map on demand. |
LazySortedMap |
Decorates another
SortedMap to create objects in the map on demand. |
LinkedMap |
A
Map implementation that maintains the order of the entries. |
ListOrderedMap |
Decorates a
Map to ensure that the order of addition is retained
using a List to maintain order. |
LRUMap |
A
Map implementation with a fixed maximum size which removes
the least recently used entry if an entry is added when full. |
MultiKeyMap |
A
Map implementation that uses multiple keys to map the value. |
MultiValueMap |
Deprecated.
since 4.1, use
MultiValuedMap instead |
PassiveExpiringMap.ExpirationPolicy |
A policy to determine the expiration time for key-value entries.
|
PredicatedMap |
Decorates another
Map to validate that additions
match a specified predicate. |
PredicatedSortedMap |
Decorates another
SortedMap to validate that additions
match a specified predicate. |
SingletonMap |
A
Map implementation that holds a single item and is fixed size. |
TransformedMap |
Decorates another
Map to transform objects that are added. |
TransformedSortedMap |
Decorates another
SortedMap to transform objects that are added. |
